When is an applicator at the greatest risk of pesticide exposure?

The applicator is at the greatest risk of pesticide exposure after mixing and loading. This stage involves handling concentrated chemicals, which can lead to increased exposure through skin contact, inhalation of dust or aerosols, and accidental spills. Mixing and loading requires careful attention to avoid overexposure due to the high concentration of the pesticides being handled.

Though the application itself can pose risks, the likelihood of severe exposure is typically highest during the mixing and loading phase where larger quantities of active ingredients are in direct contact with the applicator. Proper protective equipment and precautions are essential during this process to mitigate these risks.

Cleaning equipment, while also potentially hazardous, usually involves lower levels of residual pesticide compared to the mixing and loading phase, making it less risky in terms of acute exposure. Transportation generally involves less direct contact with pesticides, and the risk can be minimized with proper containment and handling practices.
